[Distutils] Permission Denied errors on Windows 7 with buildout 1.7.1

[Chris Withers]

Hi All,

I'm seeing this exception when running a particular buildout on Windows:

C:\Jenkins\workspace\checker-buildout\aeb5917b>bin\buildout
Develop: 'C:\\Jenkins\\workspace\\checker-buildout\\aeb5917b\\.'
Installing py.
Generated script 
'C:\\Jenkins\\workspace\\checker-buildout\\aeb5917b\\bin\\checker'.
Generated script

Generated script 
'C:\\Jenkins\\workspace\\checker-buildout\\aeb5917b\\bin\\tox-quickstart'.
While:
   Installing py.

An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:

This happens every time, on Python 2.5, 2.6 and 2.7. I've tried blowing 
the workspace away, makes no difference:

http://jenkins.simplistix.co.uk/job/checker-buildout/114/PYTHON=2.7,label=windows/console
http://jenkins.simplistix.co.uk/job/checker-buildout/114/PYTHON=2.6,label=windows/console
http://jenkins.simplistix.co.uk/job/checker-buildout/114/PYTHON=2.5,label=windows/console

Any idea what's going on here and how I can fix it?

cheers,

Chris
